[0040] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] The following describes the auxiliary tooling for welding the discharge door, the hydraulic control system of the feeding mechanism and the compression type garbage truck of the present invention with reference to the accompanying drawings.

[0042] The utility model provides a discharging door welding auxiliary tooling, such as Figure 1 and Figure 2 As shown in the figure, the auxiliary tooling for welding the unloading door includes:

[0043] The fixed support 1 is provided with a first positioning spindle 11;

[0044] A movable support 2 is longitudinally spaced apart from the fixed support 1 and is movable in the longitudinal direction, and a second positioning spindle 21 is provided on the movable support 2 and is longitudinally aligned with the first positioning spindle 11; and

[0045] The door panel bearing seat 3 is arranged between the fixed support 1 and the movable support 2 and includes a detachable door panel bearing plate 32 , on which a positioning bearing part 321 is provided. The shape of the positioning bearing part 321 is configured to imitate the cross-sectional profile of the discharge door panel 61 .

[0046] When arranging, the discharge door panel 61 is placed on the panel bearing seat 3. The positioning bearing portion 321 on the panel bearing seat 3 can be used to correct the placement posture of the discharge door panel 61. By disassembling and replacing different types of panel bearing plates 32, it is possible to accommodate the arranging and positioning of discharge door panels 61 of various sizes and shapes. The first positioning spindle 11 and the second positioning spindle 21 are mainly used to longitudinally align and position the shaft sleeves 63 of the two discharge door end plates 62. The distance between the two discharge door end plates 62 will be different for different types of discharge doors. By adjusting the distance between the fixed support 1 and the movable support 2, it is possible to accommodate the arranging of discharge door end plates 62 of different spacings. In summary, the discharge door welding auxiliary tooling in the utility model is compatible with the arranging of discharge doors of various shapes and sizes, greatly improving the compatibility of the tooling, effectively reducing the cost of fixture changeover, and improving production efficiency.

[0047] It should be noted that the unloading door welding auxiliary tooling may include multiple different types of door panel bearing plates 32. When the model of the unloading door changes, it is only necessary to replace the corresponding door panel bearing plates 32 to achieve the compatibility of the unloading door panel 61.

[0048] In the embodiments of the present invention, the cross-sectional contour wheel shape of the discharge door panel 61 mainly includes an arc shape, a bent plate shape, a stepped shape, etc. For the discharge door, the change in model is mainly for the offset distance of the discharge door panel 61 relative to the center of the shaft sleeve 63 and the cross-sectional shape and diameter of the discharge door panel 61.

[0049] When the change of the discharge door model is only for the offset distance of the discharge door door plate 61 relative to the center of the shaft sleeve 63, the door plate bearing seat 3 can be moved horizontally to reduce the number of replacement times of the door plate bearing seat 3.

[0050] Specifically, Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the door panel bearing seat 3 may further include a movable seat body 31 that can be laterally moved, and the door panel bearing plate 32 is detachably mounted on the movable seat body 31. The movable seat body 31 drives the door panel bearing plate 32 to move laterally, and the lateral position of the door panel bearing plate 32 relative to the positioning spindle can be adjusted. The position of the discharge door panel 61 relative to the positioning spindle is adjusted in advance according to the model of the discharge door. When the shaft sleeve 63 of the discharge door end plate 62 is sleeved on the positioning spindle, and the discharge door panel 61 is placed on the door panel bearing plate 32, it can be ensured that the position between the discharge door panel 61 and the shaft sleeve 63 of the discharge door end plate 62 meets the corresponding model size requirements, and the door panel bearing plate 32 does not need to be replaced during the whole process, thereby improving production efficiency.

[0051] In the embodiment of the utility model, the discharge door body can also be placed on the door panel bearing plate 32 in advance, and then the door panel bearing plate 32 drives the discharge door panel 61 to move together to adjust the deflection distance.

[0052] In the embodiment of the present invention, if the change of the discharge door model is for the size and cross-sectional shape of the door panel, it is necessary to replace the corresponding door panel bearing plate 32. The selected door panel bearing plate 32 needs to ensure that the size and shape of the positioning bearing portion 321 matches the discharge door panel 61 of the model to be mounted.

By providing the guide groove 311, the direction of the positioning bearing portion 321 can be quickly determined during the removal and replacement of the door panel bearing plate 32, ensuring that the positioning bearing portion 321 can support and position the discharge door panel 61 in the transverse direction, and by limiting the positioning bearing portion 321 to support the discharge door panel 61 in the transverse direction, the transverse direction of the discharge door panel 61 can be kept consistent with the transverse direction of the tooling after the posture of the discharge door panel 61 is corrected.

[0054] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the door panel bearing plate 32 includes a first plate body 322 for clamping with the guide groove 311 and a second plate body 323 fixed at one end on the first plate body 322, the positioning bearing portion 321 is located at the top of the first plate body 322, and the second plate body 323 is detachably connected to the movable seat body 31 through a connecting member. Specifically, the first plate bodies 322 are arranged in pairs and spaced apart to increase the stability of the support, and the second plate body 323 is connected between the paired first plate bodies 322. By arranging the second plate body 323, the door panel bearing plate 32 can form a stable structure in the shape of an "I" and facilitate the connection between the door panel bearing plate 32 and the movable seat body 31.
